TSA audit finds major security flaws at Newark Liberty Airport

NEWARK, N.J. An internal audit by the Transportation Security Administration gave failing grades to agents at Newark Liberty Airport, adding to a long list of security concerns the New Jersey airport has dealt with.

The recently released audit found that Newark TSA agents followed proper pat-down procedures just 16.7 percent of the time and confiscated banned items from carry-on luggage just 25 percent of the time, according to CBS New York affiliate WCBS.

"Obviously that's a big problem," David Katz of the Global Security Group told CBS correspondent Marcia Kramer Monday. "Newark does seem to have more than its fair share of security issues."

Last May, Homeland Security officials said Newark Liberty was the worst of six major airports when it came to security breaches.

And in August, more than 100 flights were cancelled after a passenger made it through a checkpoint without being screened properly. The airport was similarly shut down for over an hour in April after it was discovered a baby wasn't properly screened.
